Disclosed is an IR measuring instrument () comprising a least one sensor element () which is sensitive to infrared radiation and generates an output signal () that depends on the radiation incident on the at least one sensor element (). The output signal () for a predefined incident radiation can be varied by means of an integration time. The actual temperature prevailing on the at least one sensor element () is detected and is used for varying the integration time in such a way that the integration time compensates the influence of the temperature variations on the output signal () of the at least one sensor element ().

Thermographic camera

In a thermal imaging camera for acquisition of thermographic images of a measurement object, an electronic evaluation unit is integrated into the thermal imaging camera; it is designed for recognition of corresponding partial regions of the acquired thermographic images, and with it, the acquired images can be assembled into an overall image by overlapping the corresponding partial regions and displayed. The acquisition of the images preferably takes place during the swiveling of the thermal imaging camera over the solid angle region of the desired overall image.

Thermal imaging camera for taking thermographic images

In a temperature measuring device () an IR-radiation detector () and a reference element () are provided, connected to a surface () of an object () in a heat-conducting fashion, with a first area () with high emissivity and a second area () with high reflectivity formed at the reference element (), and the IR-radiation detector () is equipped for a separate detection of IR-radiation () from the first and second areas () and a surface area () of the object (). A computer () in the IR-radiation detector () is equipped to deduct a temperature measurement for the object (), corrected for emissions and reflections from the detected IR-radiations ().
